Procedure

The compound (902.3 mg) obtained in Example 102-3 was dissolved in methanol (4.0 ml) and added with a 4 mol/l hydrogen chloride/dioxane solution (4.0 ml), followed by stirring at room temperature for 8.5 hours. After the reaction, the solvent was dissolved off. The residue was added with a 1 mol/l sodium hydroxide aqueous solution (7 ml) and subjected to extraction with chloroform. Then, the extract was dried with magnesium sulfate and the solvent was dissolved off. The residue was then purified through a solid-phase extraction column (ODS type), thereby obtaining the subject compound (844.3 mg) as a brown viscous solid.
